An integrated fully enclosed cryogenic hydraulic power generation device

Abstract

The invention relates to a low-temperature hydraulic residual pressure power generation technology, in particular to an integrated totally-closed low-temperature hydraulic power generation device. Inorder to solve the technical problem that only energy can be recycled by an existing low-temperature hydraulic power generation device and energy conversion cannot be achieved, the integrated totally-closed low-temperature hydraulic power generation device provided by the invention comprises a turbine enclosure, a power generation enclosure, a main shaft, a liquid inlet runner and a liquid outletrunner, wherein one end of the power generation enclosure is connected with the turbine enclosure by an intermediate segment enclosure, the other end of the power generation enclosure is connected with an enclosure end cover, a support segment is further arranged in the intermediate segment enclosure, the main shaft penetrates through the support segment and is arranged between the turbine enclosure and the enclosure end cover, a turbine is arranged on the main shaft, a guide vane is fixedly connected with an inner wall of the turbine enclosure, an excitation machine stator winding and a powergenerator stator winding are arranged in the power generation enclosure, a excitation machine rotor winding and a power generator rotor winding are arranged on the main shaft, and the power generation enclosure communicates with a liquid outlet runner by a backflow pipe. By the device, leakage is prevented, and meanwhile, mechanical energy can be converted to electric energy to be output.

Description

technical field [0001] The invention relates to low-temperature liquefaction residual pressure power generation technology, in particular to an integrated fully enclosed low-temperature high-pressure liquid excitation power generation device. Background technique [0002] Rational use of resources is an important part of the sustainable development strategy, and the recovery and reuse of industrial waste energy is one of the key measures to implement the sustainable development strategy, which has huge development potential and economic value. [0003] At present, the power part of the low-temperature hydraulic power generation device mostly adopts the low-temperature hydraulic turbine, but the low-temperature hydraulic turbine is only an energy recovery device, and the rotating shaft passes through the casing, so there is a hidden danger of leakage of the shaft seal, and it cannot directly convert energy For electric energy, it is even more impossible to adjust the power ge...
